Agree with all the good advice to communicate with the coach.
Just a thought to add: if this is not just a matter of “dropping” a class but rather replacing it with one that better fits a student’s interests, that’s worth communicating. Often the dividing line in how this is viewed is coasting vs maintaining rigor and engagement.
If this is the only science class in the schedule, though, I’d be prepared for the coach to suggest sticking with it.
